Answer:
1 yard = 3 feet
16 yards = 16*3 feet = 48 feet
Answer:
u = x²
Step-by-step explanation:
4x⁴ − 21x² + 20 = 0
Substitute u = x² to turn the equation into a quadratic.
4u² − 21u + 20 = 0
You can solve by factoring.
(4u − 5) (u − 4) = 0
u = 5/4 or 4
x² = 5/4 or 4
x = ±½√5 or ±2
Answer:
I think its 3 if not sorry
Step-by-step explanation:
To solve this, we will need to distribute out the values in parentheses. To do this, we can use a series called the FOIL method, where we multiply the first terms, outside terms, inside terms, and last terms.
(m-7)(9m-1)
9m²-m-63m+7
9m²-64m+7
Using the math above, we can see that when we multiply these values, the answer is 9m²-64m+7.
